Are you talking about the island across from the boulders apartment complex? That's a money salmon hole if you can get to it before the guy with the mullet gets to it. Backbounce eggs on the eastside of that island, the inside seam. There's an eddy, so help it along a bit.
Or maybe you're talking about the island above greenway bridge (this is the bridge AT VRC)...those islands suck they're super shallow, but there's a nice channel going under that bridge about 20 feet from the west bank....I had some springers nail eggs under a float there, but I was in my boat. People look at you like you're a freak show when you're fishing there. "Whatcha fishing for? What, salmon? there's salmon here no way?" five minutes later the same weirdo will ask you "whatcha fishin' for?" all over again. gotta love the local "wildlife"
Orrrr maybe you're talking about the island next to the poop factory? There's a good slot on the other side of that, it's very deep, between the east side of the island and the east bank....It's within sight of beltline. Everything goes up there when the water's lower. There's usually boats anchored up above there, but it can be fished from the east bank, backbouncing or drifting eggs is good.
